SUCTION ROLL FOR PAPER-MAKING MACHINES.

Application filed. December 15, 1923.

Another object of the invention is to provide new and improved mechanism for cooperatingwith the suction roll and the suction chamber therein and permitting and adapted. for the direct drive at the suction roll.

Another object of the invention is to pro vide simple and practical mechanism for permitting' the withdrawal or removal of the suction chamber from within the suction roll. and also for permitting; the removal of a wire from the roll and replacement of an other one thereon.

Tn the accompanying drawings Fig. l is a longitudinal section of an end. portion of a 39 suction roll and suction chamber embodying my present invention;

Fig. 2 is a similar longitudinal section of the opposite end of the roll and chamber;

3 is a view of the end of the device shown in 1;

lligs. a, 5 and 6 are cross sections taken on lines 4 4 and G--6, respectively, in Fig. 2;

Figs. "4', 8, 9 and 10 are views of a conpling for connection with the suction roll for drivingthe same.

lleterring to the drawings, I show a suction roll embodying: a cylindrical portion 1 which is provided with apertures 22. This cylindric member is mounted. to rotate and to such end is provided at one end with a head 3 having; a cylindric or journal portion 4t, and at the other end with another head 5 having a cylindric bearing or journal por tion 6 which is pret'crably provided with a tapering extension 7 terminating in a reduced cylindric portion 8. The heads 3 and 5 are prcterahly secured detachably to the cylindric member 1, the head 3 by bolts 9 Serial No. 680,825.

and the head 5 by bolts 10, so that these heads may it desired, be removed as will be referred to later.

The cylindric roll thus formed is preterably mounted upon a member which forms both a rigid and stationary axis and also a suction member for use within the roll. This member conn rises a cylindric portion 11 litting within the cylindric end 4: of the head 3. said member ll. being confined within and supported by a bearing; conveniently consist- 5 ing of an upper. member 12 and a lower member 18, which are held together by bolts l4lll. winch latt r may be so tightened to cla 1p the members 12 and 18 together and thereby hold the cylindric member 11 firmly in a sta ionary condition. A collar or sleeve 15 of suitabl e bearingmetal is preferably iii-- terposed between the cylindric portion t and the member 11 to permit rotation and take up wear.

The bearing 12. 13 is conveniently mounted on a pedestal 16 which in turn is mounted on a foundation or floor 17. The pedestal 16 has a chamber 18. the upper end of which communicates with the interior 19 ot the cylindric portion 11 through an opening; 20 in the member 11. and said chamber 18 also communicates with a suction pipe 21 whereby a condition of suction or reduced air pressure may be provided in the interior of member 11.

The member 11 is preferably the end portion of a suction chamber 22 which extends lengthwise through the suction roll and whose other end is provided ith a cylindric portion 23 which forms the bearing for the rotary roll end 6, a sleeve 2% of suitable hearing metal being preferably interposed between trunnion 23 and bearing; 6. Thus the suction roll contains and revolves about the suction compartment or chamber 22 whose ends form lined shaft sections or trunnions for the cylindric ends or bearings of the suction roll.

The rotary end 6 of the suction roll is mounted in a bearing conveniently comprising; a bearing member 25 containing a sleeve 26 of suitable bearing material, in which the member 23 rests and rotates (Figs. 2 and 6).

A cap 27 is fitted upon the bearing member 25, being preferably secured thereto by screws 28 This bearing is oiled. preferably by means of an oil pipe 30, which extends from some source of oil supply into and along the interior of the suction chamber and has its end 31 connected to the member 23 and in communication with an opening therein leading to the bearing metal sleeve 24, said oil pipe having a branch pipe 30 for oiling the member 11 in bearing sleeve 15. Oil chambers 33-r 3 and oil ducts 34 and are provided for oiling the outside of the rotary end 6 and oil ducts 37-37 with an oil chamber 38 are provided for conveying oil to this bearing, an annular oil partition 40 being provided to prevent the escape of oil into the interior of the suction roll. A ring ll is mounted on the cylindric member 6 and provided with a wiper 42 in position in a recess a3 in the cap 27.

The bearing machine 25 is mounted on a pedestal and a rocking bearing is preferably provided, as by making the lower surface of said bearing 25 of circular form and providing a corresponding curved seat 4:? so as to permita moderate amount of swinging or tilting motion on the part of the member 6, and therefore on the part of the suction roll, such motion bein limited by a pin 48.

The reduced end 8 of the member 6 is extended through an aperture s 9 in another pedestal and this end 8 is subject to the action of an adjusting screw 51 carrying an end nut 52 bearing on the end 8 so that by screwing the screw 51 down pressure will be exerted on portion 8 and thereby cause said portion 8 to be depressed and consequently elevating the opposite end 11 of the suction roll about the curved bearing seat 46, the purpose o1 which will be described later on.

The end 8 is also preferably provided with a coupling by which it may bedriven from a suitable source of power, and this coupling is preferably of such nature as to take up the adjustment of the member 3 above referred to. This coupling is shown in Fig. 2 and also in Figs. 7 to 10, inclusive, and may consist of separate members 53, 54; and 55, whereof member 53 is splined or otherwise secured to member 8, and member 5% has a sliding connection with member 53, and member 55 a crosswise sliding connection with 53, and member 55 has a sliding crosswise connection with member 5a. Member 55 is understood to be splined or otherwise secured to a rotary shaft 56 extending to a suitable source of power.

The suction chamber 22 is arranged so that its upper portion may be adjusted relatively to the inside of the suction roll cylinder 1 so as to secure a tight contact therewith, and provision is made for varying this adjust inent in accordance with circumstances and various requirements, and also a deckel arrangement is preferably provided for accommodating dili'erent widths of paper.

flexible material are secured to member 60 by screws 61 and will be sucked against ends of shoulder 22 and of members 6l61, so as to make air tight joints at the ends of suction chamber. The member 60 carries longitudinally extending laminated brushes 62 and transversely extending laminated brushes 63 connecting the brushes 62 at their ends, and the brushes 63 are mounted on slidestlt and adapted to slide longitudinally of the suction roll and so move the brushes 63 to cover more or less of the roll apertures 22, and so accommodate the roll for diiterent widths of paper.

The slides 64 and 65 are connected by pins 66 with the brackets 67 in turn pivoted at 68 to collars 69 and 70, whereof the collar 69 is mounted on a tubular rod 71 and the collar 70 on a rod 72 contained within and arranged to slide relatively to the rod 71. These rods 71 and '72 extend out through the left hand end of the suction chamber and are provided the rod 71 with a rotary adjusting wheel 7 3, and the rod 72 with an adjusting wheel 74, whereby either one or both of these wheels 73 and 74: may be turned so to adjust the brushes 63-63 in the manner and for the purpose above set forth.

In order to adjust the upper portion of the suction chamber vertically to secure and maintain an air tight connection with the suction roll, a rod 7 5 is extended longitucinally within the suction chamber and connected by pins 7 6 with swinging levers 77 which are pivoted at 78 on fixed brackets '59, the upper ends of said levers 77 being in engagement with the upper suction roll member 60 preferably through the medium oi adjusting screws 80 which permit adjustment so that all of said levers may be similarly arranged for movement of the'upper portion or part of the suction roll. The rod '4' 5 extends preferably through the left hand end of the suction chamber and is provided with a spring 82 subjecting it to pressure tending to move it to the left referring to Fig. 1, and thereby cause the levers '77 to exert an upward pressure on the upper por tion of the suction chambeiyrto cause a tight joint between the same and the interior surrace 01" the suction roll. Rod 75 is provided with a threaded end 8% on which is mounted a nut 85 to permit adjustment of tension of spring 82'and thereby cause desired variations in the pressure of the suction chamber upon the suction roll. It will be seen that this adjustment of the suction chamber may be made as 'desired by the mechanical means provided and may be independent of the suction pressure within the suction chamber.

As a matter of further improvement in the mounting of the roll, the bearing block 13 is mounted on the pedestal 16 in such manner that said block 18 may be lifted slightly above the pedestal 16 and the latter is provided with a side extension 87 (Fig. 3), which is pivoted by bolt 88 to the foun dation member 1'? so that said member 16 may be swung out from under the member 13. This is done in order to permit changing of a wire, the m mber l6 being moved outtrom under member 13' to permit the wire to be slid over and around the suction roll. The lifting of the member 13 to permit member 16 to be swung out into sidewise position, as indicated in dotted lines in Fig. 3, may be accomplished by actuating screw 51 so as to depress the contracted roll end 8, the depressing oi this end tilting the other end of the roll upward, and thereby lifting the member 13 slightly.

As a matter of still further improven'ientthe suction chamber is preferably provided with wheels or rollers 90 (Fig. 2), conveniently secured to the under side of said chamber and adapted to roll on the under portion oi the cylindric member 1, whereby the suction chamber may be removed from the suction roll for purposes oil repair replacement, when this takes place the axle or trunnion end 23 simply being withdrawn from within the roll end 6, and when the suction chamber is replaced the tapering end of the member 23 permits the proper fitting together of the parts. The roll or wheel 90 is preferably mounted so that it will. normally be slightly above the roll sur face, thereby permitting rotation of the latter without any interference by said wheel 90.

lit will be seen that the construction permits a direct drive or the suction roll through the medium of the drive connection 53, 554i and or through the medium of other com ctions or couplin it may be desired to use. This dispe. ses with inte-7- mediate gears and simplifies and cheapens construction, as well. as yielding the well .mown advantages of direct drive.
